Evaluation of Conventional and Long Pulse Widths During a Temporary Spinal Cord Stimulation Trial

Amol Soin10 enrolled

Overview

The purpose of this study is to evaluate the effect of pulse widths \<500 µS and \>1000 µS on clinical outcomes during a temporary SCS trial.

The proposed study is a prospective, single-center, two arm, randomized, crossover design to be conducted at The Ohio Pain Clinic. The study will enroll up to 15 subjects in order to include up to 10 subjects in the study. Subjects selected to participate in the trial have back and/or leg pain, have been evaluated as a candidate for SCS and have agreed to undergo a temporary SCS trial using the Algostim system with percutaneous leads. Each subject will be followed during the trial period of approximately 7 days. The study will end when the last subject has completed the trial period. exited. The expected enrollment period for this study is approximately three months. After exit from the clinical study, subjects will continue to be followed by their physician per usual care. All device and procedure-related AEs will be collected and reported per the study protocol.

Outcomes

Primary Outcomes

Subject Pain Relief

The study used a pain relief scale (similar to a brief pain inventory). The scale assessed pain relief using a percent relief rating in 10% increments, where a higher number represents greater pain relief than a lower number for the pain scale. A higher number is considered better for pain relief scale. The scale range is from 0%, which is no relief of pain to 100%, which is complete relief of pain. Subjects are asked to rate their pain by marking the box beside the number that best describes their pain in the last 24 hours.

Time frame: up to 8 days

Secondary Outcomes

Distribution of Paresthesia

1\. At end of each arm, subjects will be asked to complete a diagram that shows distribution of paresthesia.

Time frame: Up to 8 days

Subject Preference

Subjects will be asked to select their favorite program

Time frame: Up to 8 days

Quality of Pain Relief

Subjects will be asked to rate the quality of the pain relief achieved during the trial (from either arm) using the following scale; Excellent, Very Good, Good, Fair or Poor

Time frame: Up to 8 days

Subject Satisfaction

Subjects will be asked to rate their overall satisfaction with the pain relief achieved during the trial (from either arm) using the following scale; Very Satisfied, Satisfied, Neither Satisfied nor Unsatisfied, Unsatisfied or Very Unsatisfied

Time frame: Up to 8 days

Achievement of ≥50% Pain Relief

Number of patients who achieved ≥ 50% pain relief during the trial (from either arm). The study used a pain relief scale (similar to a brief pain inventory). The scale assessed pain relief using a percent relief rating in 10% increments, where a higher number represents greater pain relief than a lower number for the pain scale. A higher number is considered better for pain relief scale.
